Stale partitions are listed on creating a virtual disk for Linux
Description: When a virtual disk is created using physical disks that were earlier used for creating Linux virtual disk, we
see some Linux partitions present during OS installation.
Solution Whenever we create or delete a virtual disk, only the superblock metadata is modified. The partition table
of the virtual disk which is stored at logical LBA-0 is not modified. Hence when we re-create a virtual disk,
we still see the previous partitions being listed.
● During OS installation these partitions can be deleted using the OS installer.
● To not list the partitions, if supported you can perform cryptographic erase of the physical disk and
then create a virtual disk from the HII.
NOTE: Performing cryptographic erase will delete all the data on the physical disk.
Rebuilding a virtual disk the global hot spare is not listed as online
in HII or iDRAC
Description: After the rebuild of a virtual disk is completed using the global hot spare the status of the disk is not listed
as online, instead the status of the disk is listed as ready.
Solution This is an expected behavior. No action is required.
Virtual disk size in decimals is not supported while creating a VD
Likely Cause:
After entering the disk size value, changing the virtual disk size unit from MB to GB or GB to TB and so
on changes the disk size value.
Corrective
Action:
It is recommended to select the virtual disk size unit before specifying the disk size value.
Cannot create a virtual disk
If you are unable to create a virtual disk, check the following causes:
1. The physical disk is not displayed.
2. Insufficient free space available on the selected physical disks.
3. Incorrect number of physical disks selected for the desired RAID level on page 52.
4. The desired physical disk is unavailable.
5. The system already has a maximum of 30 virtual disks on page 52.
The physical disk is not displayed
This error might be because:
1. The controller cannot communicate with the physical disks.
2. A cable might be loose or defective.
3. The physical disk might be a SAS drive.
Re-seat the physical disks in the backplane and check their cables.
Insufficient free space available on the selected physical disks
There must be sufficient available free space on the physical disk used by the virtual disk.
